OPHTHALMIC MlDU'NTING.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed October 6, 1917. Serial No. 195,015.

To all whom it may concern:

Be it known that I, HARRY H. Sam, a citizen of the United States, residing at Southbridge in the county of Worcester and State of Massachusctts have invented certain new and useful Improvements in O hthalmic l dountings, of which the followlng is a specification.

This invention comprchcnds new and useful improvements in ophthalmic mountings and. relates particularly to an improved form. of mounting or frame of what is commonl I known as the combination type made up 0' combined metal and xylonite or other non-metallic parts.

One of the main objects of thisinvention relates to an improved frame having novel means for uniting and securely retaining against relative movement the metallic and non-metallic parts.

Another object of the invention isthe pro vision of a mounting of this character wherein the non-metallic ring is of a continuous unbroken piece while the metallic member may be constructed of either a continuous member or a split ring as desired and applied to the non-metallic member in such a manner as to securely clamp the lens in its operative position.

With the above and other objects in view, the invention consists in the novel features of construction and the combination and arranginent of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which Figure I is front elevation of a pair of eyeglasses illustrating my improved mounting.

Fig. IX is a sectional view showing an other method of attaching the fittings to the metallic rim.

In carrying out my invention I provide a frame 1 which includes the non-metallic ring 2 and the metallic ring 3. This non-metallic ring 2 is preferably made of xylonite or any similar material and includes the main body portion having formed within its inner face a circumferential groove 5 having inclined walls, said groove being adapted to receive the circumferential edge of the lens 6. It will be understood that the annular portion 7 projeoting'beyondthe groove 5 contains sufficient resiliency to permit the lens 6 to be forced through the same and into the groove 5, theinclined portions 8- of the lens abutting the inclined Walls of the groove to prevent any" lateral movement of the lens after being forced into the groove.

As clarly illustrated in ig. II the body 43 of the non-metallic ring 2 is provided upon one side thereof with the singularly projecting annular flange 9 and arranged within this flange is the metallic ring 3 which is of a continuous piece. This metallic ring 3 when in position is securely held agalnst relative movement by means of the small screw members 10 which extend through the annular flange 9 and into the ring 3. F ile I have illustrated the use of screws 10 as the preferred form of fastening devic s it will be understood that rivets or sim' a means may be used. The use of the screws as means for securing the metalli' and nonmetallic rings together is prefer ed in view of the fact that they can be readily removed to detach the ring 3 from the ring 2. It will be apparent that when the ring 3 is in position within the flange 9 it will tend to retain the annular portion 7 ina normal outstanding position and 'thus keep the lens 6 within its proper position however it will be understood that with a little force the lens can be readily forced beyond the annular member 7 and into the groove 5 and can also be removed by pressing outwardly on the lens near the flange thus forcing the edge of members interiorly engaging the non-metal- In testimony whereef I have eed. my

lie members f0;1 bracing the same find aiding signature, in presence of two Witnesses.
